Thanks guys for the responses
It is for currency conversion. The UK is not important but would be nice to be able to operate there if required also the cost of £300 sounds quite attractive.
I would like to set up in France.
Sols you put "You'll need at least 50,000 EUR but realistically more like 100,000 EUR to get the license, plus costs of running and operating the business." if this is to prove we have the funds to operate that is fine but if that is the fee for getting a license then it would be too much to pay for what I have in mind.
Any more information would be appreciated
